Any low-expansion, closed cell foam will serve you well... I recently saw a demo of several different products which showed how much material is actually in each can (was an eye-opener ), however, that is really only a concern for those of us who use a high volume. The Osi/Henkel Winteq product has been my choice over the past couple years.... (The Great Stuff fared worst in the test).

I personally like the OSI TeQ-foam and Premier. They seem to be the same formula and act the same. Dow would be my least favorite as the bead seems to bubble up a lot and separate requiring multiple passes. Hilti makes a nice product, however the expansion rate seems to be more aggressive than that of the OSI and can throw my bead application off at first if I've not used the Hilti foam in a while. At double the price I can't find a justified reason to utilize Hilti either?

The OSI expands quicker and sets faster than the Dow product.It also propels all of the contents of the can more quickly and efficiently. I would not take a chance with Dap or anything latex.Keep in mind most here are sharing there experience using a professional foam applicator gun. The gun is the prefered dispenser for it's adjustability,ease of use and storage.
